    ImageBitmapLoader

    An ImageBitmap provides an asynchronous and resource efficient pathway to prepare textures for rendering.

    Note that Texture#flipY and Texture#premultiplyAlpha are ignored with image bitmaps. -They needs these configuration on bitmap creation unlike regular images need them on uploading to GPU.

    -

    You need to set the equivalent options via ImageBitmapLoader#setOptions instead.

    -

    Also note that unlike FileLoader, this loader avoids multiple concurrent requests to the same URL only if Cache is enabled.

    -

    Code Example

    - 
    const loader = new THREE.ImageBitmapLoader();
+These options need to be configured via ImageBitmapLoader#setOptions prior to loading,
+unlike regular images which can be configured on the Texture to set these options on GPU upload instead.
    
+
    To match the default behaviour of Texture, the following options are needed:
    
+
    Also note that unlike FileLoader, this loader will only avoid multiple concurrent requests to the same URL if Cache is enabled.

    const loader = new THREE.ImageBitmapLoader();
 loader.setOptions( { imageOrientation: 'flipY' } ); // set options if needed
 const imageBitmap = await loader.loadAsync( 'image.png' );
 const texture = new THREE.Texture( imageBitmap );
